The article documents a new species of dragonfly-and damselfly relative, Brunellopteron norradi, based on a specimen found in Canada. It displays unique wing venation patterns and may be closely related to a species from the Moscovian of northern France.
A stem relative of dragon- and damselflies, Brunellopteron norradi Bethoux, Deregnaucourt and Norrad gen. et sp. nov., is documented based on a specimen found at Robertson Point (Grand Lake, New Brunswick, Canada; Sunbury Creek Formation; early Moscovian, Pennsylvanian) and preserving the basal half of a hindwing. A comparative analysis of the evolution of wing venation in early odonates demonstrates that it belongs to a still poorly documented subset of species. Specifically, it displays a MP + CuA fusion, a CuA + CuP fusion, and a CuP + AA fusion, but it lacks the extended MP + Cu/CuA fusion and the extended (CuP = CuA + CuP) + AA fusion, the occurrence of which is typical of most Odonata, including Meganeura-like species. The occurrence of intercalary veins suggests that its closest relative might be Gallotypus oudardi Nel, Garrouste and Roques, 2008, from the Moscovian of northern France.
